A compound neural response equals single-fiber waveforms convolved with the discharge timing distribution

Evidence

The recorded compound action potential (CAP ) is described as the convolution of the unit response (UR , i.e., the waveform resulting from a single action potential) with the compound discharge latency distribution (CDLD ), the sum of spike events over time of all individual nerve fibres (Goldstein and Kiang 1958 , see also Fig. 1 ). (1) This mathematical model was validated with simultaneous recordings of acoustically evoked CAPs from the round window and single-fibre responses from the auditory nerve in guinea pigs (Versnel et al. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2386
